Hi,

I agree 100% with Michael Tuexen here... just one thing, in line:


>> You're right, SCTP is non-deployable, which makes it a non-starter.  SCTP also does not address handshake issues or TLS issues.
> I agree that SCTP over IP can't be deployed now due to missing NAT support.

Indeed that's not an argument against SCTP/UDP/IP, but I also wonder why, instead of saying "can't be deployed", people don't just go ahead and use it whenever it's there and works, with a fall-back to TCP? This could be done with (this version of) Happy Eyeballs:
http://tools.ietf.org/html/draft-wing-tsvwg-happy-eyeballs-sctp-02

Good reasons against doing this are... what? Anyone?

Cheers,
Michael
